underscore: Version 1.9.2 no longer works with ExtendScript .jsx

// #include "underscore-1.8.3.js"
#include "underscore-1.9.2.js"

var artists = ['Pharrel Williams', 'Led Zeppelin', 'Rolling Stones'];

_.each(artists, function(artist, index, artists) {
  alert('artist: ' + artist);
});

Error : _ is undefined

Now try version 1.8.3 it works like a charm
